Mesenchymal stem cells (MSCs) are promising multipotent cells with applications for cartilage tissue regeneration in stem cell-based therapies. In cartilage regeneration, both bone marrow (BM-MSCs) and synovial fluid (SF-MSCs) are valuable sources. However, the cellular characteristics and chondrocyte differentiation potential were not reported in either of the camel stem cells. The in vitro chondrocyte differentiation competence of MSCs, from (BM and SF) sources of the same Camelus dromedaries (camel) donor, was determined. Both MSCs were evaluated on pluripotent markers and proliferation capacity. After passage three, both MSCs showed fibroblast-like morphology. The proliferation capacity was significantly increased in SF-MSCs compared to BM-MSCs. Furthermore, SF-MSCs showed an enhanced expression of transcription factors than BM-MSCs. SF-MSCs exhibited lower differentiation potential toward adipocytes than BM-MSCs. However, the osteoblast differentiation potential was similar in MSCs from both sources. Chondrogenic pellets obtained from SF-MSCs revealed higher levels of chondrocyte-specific markers than those from BM-MSCs. Additionally, glycosaminoglycan (GAG) content was elevated in SF-MSCs related to BM-MSCs. This is, to our knowledge, the first study to establish BM-MSCs and SF-MSCs from the same donor and to demonstrate in vitro differentiation potential into chondrocytes in camels.

Horses are widely used as large animal preclinical models for cartilage repair studies, and hence, there is an interest in using equine synovial fluid-derived mesenchymal stem cells (SFMSCs) in research and clinical applications. Since, we have previously reported that similar to bone marrow-derived MSCs (BMMSCs), SFMSCs may also exhibit donor-to-donor variations in their stem cell properties; the current study was carried out as a proof-of-concept study, to compare the in vivo potential of equine BMMSCs and SFMSCs in articular cartilage repair. MSCs from these two sources were isolated from the same equine donor. In vitro analyses confirmed a significant increase in COMP expression in SFMSCs at day 14. The cells were then encapsulated in neutral agarose scaffold constructs and were implanted into two mm diameter full-thickness articular cartilage defect in trochlear grooves of the rat femur. MSCs were fluorescently labeled, and one week after treatment, the knee joints were evaluated for the presence of MSCs to the injured site and at 12 weeks were evaluated macroscopically, histologically, and then by immunofluorescence for healing of the defect. The macroscopic and histological evaluations showed better healing of the articular cartilage in the MSCs’ treated knee than in the control. Interestingly, SFMSC-treated knees showed a significantly higher Col II expression, suggesting the presence of hyaline cartilage in the healed defect. Data suggests that equine SFMSCs may be a viable option for treating osteochondral defects; however, their stem cell properties require prior testing before application.

Abstract Human bone marrow contains a rare population of non-hematopoietic mesenchymal stromal cells (BM-MSC) with multilineage differentiation capacity, which are essential constituents of the hematopoietic microenvironment. Self-renewal and differentiation are the two key properties of somatic stem cells, however, stem cell properties of human adult BM-MSC have not been demonstrated conclusively yet. We have previously shown that low/negative expression of PDGFRα on linneg/CD45neg/CD271pos cells identified a highly enriched population of primary BM-MSC in adult human bone marrow (Li et al. Blood, 2013, 122:3699). Based on this work, the current study aimed to investigate the in-vitro and in-vivo stem cell properties of this putative stromal stem cell population. The in-vitro clonogenic potential of freshly sorted human linneg/CD45neg/CD271pos/PDGFRlow/neg cells was evaluated by utilizing the CFU-F assay as well as the recently-developed mesensphere assay, which enables MSC amplification while preserving an immature phenotype (Isern et al, Cell Reports 2013, 30: 1714-24). Comparable colony frequencies were obtained with both assays (19.3 ± 2 and 17.5 ± 2.3 CFU-F and spheres per 100 plated cells, respectively, n=6, p=0.19). In order to test whether both assays identified the same population of clonogenic cells, colonies and spheres were replated under both conditions for up to three generations. The results showed comparable capacities of CFU-F and mesenspheres to form secondary and tertiary CFU-F and spheres. In-vitro self-renewal as indicated by increasing numbers of CFU-F and spheres (416.6 ± 431.7-fold and 49.5 ± 65.7-fold, respectively, n=3) was observed up to the third generation and decreased thereafter. The total number of generations was five (CFU-F) and six (spheres). In-vitro differentiation assays with both, CFU-F- and sphere-derived cells (tested until passage three) demonstrated tri-lineage differentiation potential (adipocytes, osteoblasts, chondrocytes). In addition, CFU-Fs and spheres had comparable surface marker profiles (CD73, CD90, CD105, and HLA-ABC positive; CD31, CD34 and HLA-DR negative), except for CD90, which was higher expressed on CFU-Fs. To investigate in-vivo self-renewal and differentiation potential of the putative stromal stem cells, linneg/CD45neg/CD271pos/PDGFRlow/neg -derived CFU-F and spheres were serially transplanted s.c into NSG mice. After 8 weeks, implants were harvested, human cells were FACS-isolated (CD90 and CD105 expression), and re-assayed under CFU-F and sphere conditions. Whereas in-vivo self-renewal of CFU-F could not be shown (111.5 ± 36 –fold decrease in total CFU-F numbers after primary transplantation, n=3), sphere self-renewal was clearly demonstrated by increased numbers of spheres after primary as well as secondary transplantation (1.13 ± 0.05 and 2.06 ± 0.26 –fold, respectively, n=3), which is remarkable given the fact that the number of recovered human cells is underestimated due to the isolation approach. Here, confirming GFP-marking experiments are ongoing. Finally, preliminary data indicate that linneg/CD45neg/CD271pos/PDGFRlow/neg –derived spheres display full in-vivo differentiation capacity in primary and secondary transplantations. Taken together, our data demonstrate - for the first time - that primary human linneg/CD45neg/CD271pos/PDGFRlow/neg cells meet stringent stem cell criteria, i.e. in-vitro and in-vivo self-renewal and differentiation. These findings answer the long-open question of the potential stem cell properties of adult human MSC and will enable to better understand the properties of native BM-MSC and their biological role in the bone marrow.

Differentiation Potential

BACKGROUND: Cell therapies offer a promising potential in promoting bone regeneration. Stem cell therapy presents attractive care modality in treating degenerative conditions or tissue injuries. The rationale behind this is both the expansion potential of stem cells into a large cell population size and its differentiation abilities into a wide variety of tissue types, when given the proper stimuli. A progenitor stem cell is a promising source of cell therapy in regenerative medicine and bone tissue engineering. AIM: This study aimed to compare the osteogenic differentiation and regenerative potentials of human mesenchymal stem cells derived from human bone marrow (hBM-MSCs) or amniotic fluid (hAF-MSCs), both in vitro and in vivo studies. SUBJECTS AND METHODS: Human MSCs, used in this study, were successfully isolated from two human sources; the bone marrow (BM) and amniotic fluid (AF) collected at the gestational ages of second or third trimesters. RESULTS: The stem cells derived from amniotic fluid seemed to be the most promising type of progenitor cells for clinical applications. In a pre-clinical experiment, attempting to explore the therapeutic application of MSCs in bone regeneration, Rat lumbar spines defects were surgically created and treated with undifferentiated and osteogenically differentiated MSCs, derived from BM and second trimester AF. Cells were loaded on gel-foam scaffolds, inserted and fixed in the area of the surgical defect. X-Ray radiography follows up, and histopathological analysis was done three-four months post- operation. The transplantation of AF-MSCs or BM-MSCs into induced bony defects showed promising results. The AF-MSCs are offering a better healing effect increasing the likelihood of achieving successful spinal fusion. Some bone changes were observed in rats transplanted with osteoblasts differentiated cells but not in rats transplanted with undifferentiated MSCs. Longer observational periods are required to evaluate a true bone formation. The findings of this study suggested that the different sources; hBM-MSCs or hAF-MSCs exhibited remarkably different signature regarding the cell morphology, proliferation capacity and osteogenic differentiation potential CONCLUSIONS: AF-MSCs have a better performance in vivo bone healing than that of BM-MSCs. Hence, AF derived MSCs is highly recommended as an alternative source to BM-MSCs in bone regeneration and spine fusion surgeries. Moreover, the usage of gel-foam as a scaffold proved as an efficient cell carrier that showed bio-compatibility with cells, bio-degradability and osteoinductivity in vivo.

Human multipotent stem cell-based therapies have shown remarkable potential in regenerative medicine and tissue engineering applications due to their abilities of self-renewal and differentiation into multiple adult cell types under appropriate conditions. Presently, human multipotent stem cells can be isolated from different sources, but variation among their basic biology can result in suboptimal selection of seed cells in preclinical and clinical research. Thus, the goal of this study was to compare the biological characteristics of multipotent stem cells isolated from human bone marrow, placental decidua basalis, and urine, respectively. First, we found that urine-derived stem cells (USCs) displayed different morphologies compared with other stem cell types. USCs and placenta decidua basalis-derived mesenchymal stem cells (PDB-MSCs) had superior proliferation ability in contrast to bone marrow-derived mesenchymal stem cells (BMSCs); these cells grew to have the highest colony-forming unit (CFU) counts. In phenotypic analysis using flow cytometry, similarity among all stem cell marker expression was found, excluding CD29 and CD105. Regarding stem cell differentiation capability, USCs were observed to have better adipogenic and endothelial abilities as well as vascularization potential compared to BMSCs and PDB-MSCs. As for osteogenic and chondrogenic induction, BMSCs were superior to all three stem cell types. Future therapeutic indications and clinical applications of BMSCs, PDB-MSCs, and USCs should be based on their characteristics, such as growth kinetics and differentiation capabilities.

Mesenchymal stem cells (MSCs) are promising candidates for tissue regeneration and disease treatment. However, long-term in vitro culture results in loss of MSC stemness. The inflammation that occurs at stem cell transplant sites (such as that resulting from TNF-α) is a contributing factor for stem cell treatment failure. Currently, there is little evidence regarding the protective role of melatonin with regard to the negative effects of TNF-α on the stemness of MSCs. In this study, we report a melatonin-based method to reduce the inflammatory effects on the stemness of bone marrow mesenchymal stem cells (BMMSCs). The results of colony formation assays, Alizarin red staining, western blotting, and reverse transcription-polymerase chain reactions suggest that melatonin can reverse the inflammatory damage caused by TNF-α treatment in the third, seventh, and tenth generations of primary BMMSCs (vs. control and the TNF-α-treated group). Meanwhile, a detailed analysis of the molecular mechanisms showed that the melatonin receptor and YAP signaling pathway are closely related to the role that melatonin plays in negative inflammatory effects against BMMSCs. In addition, in vivo experiments showed that melatonin could reverse the damage caused by TNF-α on bone regeneration by BMMSCs in nude mice. Overall, our results suggest that melatonin can reverse the loss of stemness caused by inflammatory factor TNF-α in BMMSCs. Our results also provide a practical strategy for the application of BMMSCs in tissue engineering and cell therapy.

Mesenchymal Progenitors

Several cell populations derived from bone marrow (BM) have been shown to possess cardiac regenerative potential. Among these are freshly isolated CD133+ hematopoietic as well as culture-expanded mesenchymal stem cells. Alternatively, by purifying CD271+ cells from BM, mesenchymal progenitors can be enriched without an ex vivo cultivation. With regard to the limited available number of freshly isolated BM-derived stem cells, the effect of the dosage on the therapeutic efficiency is of particular interest. Therefore, in the present pre-clinical study, we investigated human BM-derived CD133+ and CD271+ stem cells for their cardiac regenerative potential three weeks post-myocardial infarction (MI) in a dose-dependent manner. The improvement of the hemodynamic function as well as cardiac remodeling showed no therapeutic difference after the transplantation of both 100,000 and 500,000 stem cells. Therefore, beneficial stem cell transplantation post-MI is widely independent of the cell dose and detrimental stem cell amplification in vitro can likely be avoided.

Background: Several studies have shown the relationship between poorer clinical outcomes of arthroscopic femoroacetabular impingement syndrome surgery and focal chondral defects or global chondromalacia/osteoarthritis. Although recent studies described good outcomes after the conjunctive application of synovial mesenchymal stem cells (MSCs), none demonstrated the application of synovial MSCs for cartilaginous hip injuries. Purpose: To compare the characteristics of MSCs derived from the paralabral synovium and the cotyloid fossa synovium and determine which is the better source. Study Design: Controlled laboratory study. Methods: Synovium was harvested from 2 locations of the hip—paralabral and cotyloid fossa—from 18 donors. The number of cells, colony-forming units, viability, and differentiation capacities of adipose, bone, and cartilage were collected and compared between groups. In addition, real-time polymerase chain reaction was used to assess the differentiation capacity of adipose, bone, and cartilage tissue from both samples. Results: The number of colonies and yield obtained at passage 0 of synovium from the cotyloid fossa was significantly higher than that of the paralabral synovium ( P < .01). In adipogenesis experiments, the frequency of detecting oil red O–positive colonies was significantly higher in the cotyloid fossa than in the paralabral synovium ( P < .05). In osteogenesis experiments, the frequency of von Kossa and alkaline phosphatase positive colonies was higher in the cotyloid fossa synovium than in the paralabral synovium ( P < .05). In chondrogenic experiments, the chondrogenic pellet culture and the gene expressions of COL2a1 and SOX9 were higher in the cotyloid fossa synovium than in the paralabral synovium ( P < .05). Conclusion: MSCs from the cotyloid fossa synovium have higher proliferation and differentiation potential than do those from the paralabral synovium and are therefore a better source. Clinical Relevance: Synovial cells from the cotyloid fossa synovium of patients with femoroacetabular impingement syndrome are more robust in vitro, suggesting that MSCs from this source may be strongly considered for stem cell therapy.

Differentiation Potential

Mesenchymal stem cells (MSC) are isolated from bone marrow or other tissues, and have properties of self renewal and multilineage differentiation ability. The current study investigated the in vitro differentiation potential of porcine bone marrow derived MSCs into hepatocyte-like cells. The MSC were isolated from the bone marrow of adult miniature pigs (7 months old, T-type, PWG Micro-pig®, PWG Genetics, Seoul, Korea) and adherent cells with fibroblast-like morphology were cultured on plastic. Isolated MSCs were positive for CD29, CD44, CD73, CD90, and vimentin, and negative for CD34, CD45, major histocompatibility complex-class II (MHC-class II), and swine leukocyte antigen-DR (SLA-DR) by flow cytometry analysis. Further, trilineage differentiation of MSC into osteocytes (alkaline phosphatase, von Kossa and Alizarin red), adipocytes (Oil Red O), and chondrocytes (Alcian blue) was confirmed. Differentiation of MSC into hepatocyte-like cells was induced with sequential supplementation of growth factors, cytokines, and hormones for 21 days as described previously (Taléns-Visconti et al. 2006 World J. Gastroenterol. 12, 5834–5845). Morphological analysis, expression of liver-specific markers, and functional assays were performed to evaluate the hepatic differentiation of MSC. Under hepatogenic conditions, MSC acquired cuboidal morphology with cytoplasmic granules. These hepatocyte-like cells expressed α-fetoprotein (AFP), albumin (ALB), cytokeratin 18 (CK18), cytochrome P450 7A1 (CYP7A1), and hepatocyte nuclear factor 1 (HNF-1) markers by immunofluorescence assay. In addition, the expression of selected markers was demonstrated by Western blotting analysis. In accordance with these features, RT-PCR revealed transcripts of AFP, ALB, CK18, CYP7A1, and HNF-1α. Further, the relative expression levels of these transcripts were analysed by quantitative RT-PCR after normalizing to the expression of the endogenous control, glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Data were analysed statistically by one-way ANOVA using PASW statistics 18 (SPSS Inc., Chicago, IL, USA), and significance was considered at P < 0.05. The results showed that the relative expressions of selected marker genes in hepatocyte-like cells were significantly increased compared with that in untreated MSC. The generated hepatocyte-like cells showed glycogen storage as analysed by periodic acid-Schiff (PAS) staining. Moreover, the induced cells produced urea at Day 21 of culture compared with control MSC. In conclusion, our results indicate the potential of porcine MSC to differentiate in vitro into hepatocyte-like cells. Further studies on the functional properties of hepatocyte-like cells are needed to use porcine MSC as an ideal source for liver cell therapy and preclinical drug evaluation.
